An Intelligent Renewable Energy Distribution Strategy for Off-line Fare Meter

This paper designs an intelligent solar energy storage system for off-line electronic devices, which collects solar energy through solar panels and stores it in a storage system. The energy storage components include a set of supercapacitor and two sets of lithium-ion battery packs. An intelligent energy storage and discharging optimization strategy is adopted to allocate energy effectively between the supercapacitor and lithium-ion battery packs, which enabling the two sets of lithium-ion battery packs to alternate between energy storage to achieve uninterrupted power supply for the load system. The experimental results show that the total conversion efficiency of the intelligent power distribution system (including the self-powered system) can reach up to 89.32%.
